Values[edit]

Values indicate the level of support in the most recent version of the layout engine, or (if a version number is given) in the specified version. Version numbers without any other value indicate the version at which the layout engine first fully supported the feature.

Value Meaning
Yes Indicates that the layout engine fully supports this property/element when valid values are used.
No Indicates that the property/element is completely ignored.
Partial Indicates that the property/element is understood, but that not all values are supported. Supported values are implemented correctly.
Incorrect Indicates that the property/element is understood, but that it is not implemented correctly in all cases.
Experimental Indicates that the property/element is understood, but supported under an alternate name. May be incomplete or buggy.
Dropped Indicates that the property/element is no longer supported.
Nightly build Indicates that the property/element is supported to some extent in an experimental/nightly build. Future support is expected.
Depends Indicates that the property/element is supported only on certain platforms, or if certain settings are configured.
